Congressman Frank Pallone says the State Department needs to reassess the travel advisory.

"I urge you to provide the bereaving families with consistent updates as the Department of State works with the FBI and the Government of the Dominican Republic to determine the cause of death for these individuals," says Pallone.

Currently, the travel advisory is level two for the country – meaning exercise increased caution.
